Method and apparatus for mounting a lens

摘要

An apparatus is described for mounting an actuator lens within an optical disc carriage held by a baseplate assembly. The apparatus includes a frame, a cradle assembly mounted to the frame with at least one degree of freedom of motion, a tower assembly mounted to the frame, a lever assembly rotatably mounted to the frame, and a gripper assembly mounted to the lever assembly. The cradle assembly includes a baseplate alignment assembly having a source of radiant energy for projecting a beam of radiant energy, means for determining the tilt alignment of the beam with respect to the tower assembly, and a plurality of tilt actuators for aligning the tilt of the beam with respect to the tower assembly. The tower assembly includes a video camera having a camera lens, a tower magnifying lens, and a monitor for displaying a presentation of a beam of radiant energy passing through the tower magnifying lens and into the video camera. A method for mounting a lens is described which includes the steps of placing a lens in the carriage, aligning the lens by moving a baseplate assembly with respect to the tower assembly, moving the objective lens assembly with respect to the tower assembly, and moving the actuator lens with respect to the tower assembly. The lens is attached to the gripper assembly and the lever moves the gripper and lens away from the carriage. Adhesive is applied to the carriage and the lever is moved back so as to place the lens on the adhesive in the aligned position.
